Only these two options are characteristics of a ray when it is refracted, but not when it is reflected. In fact: Reflection occurs when a ray hits the interface between two mediums and bounces off back. When it is reflected, the ray changes direction, but does not change speed since it does not change medium.
Which are characteristics of a ray when it hits a boundary and refracts but not when?

What are the characteristics of a ray when it hits a boundary and refracts?
In reflection, rays bounce off a boundary, and in
refraction, rays pass through a boundary
. A ray diagram is shown.
What happens to light rays when they hit a boundary?
A light wave transports energy from one location to another. When a light wave strikes a boundary between two distinct media,
a portion of the energy will be transmitted into the new medium and a portion of the energy will be reflected off the boundary and stay within the original medium
.
What happens to the incident ray when it hits the boundary and enters into the air from water is the ray bent toward the normal line or bent away from the normal?
As the light enters the water,
it is refracted
. Since the light is passing from air (less dense) into water (more dense), it is bent towards the normal.
Which best describes Sawyer’s error?
Which best describes Sawyer’s error?
The wave fronts should be perpendicular to the direction in which the waves move
.
Who gave Snell’s law?
Open any physics textbook and you’ll soon come across what English-speaking physicists refer to as “Snell’s law”. The principle of refraction – familiar to anyone who has dabbled in optics – is named after
the Dutch scientist Willebrørd Snell
(1591–1626), who first stated the law in a manuscript in 1621.
What are the characteristics of a ray?
In geometry, a ray can be defined as a part of a line that has a fixed starting point but no end point.
It can extend infinitely in one direction
. On its way to infinity, a ray may pass through more than one point.
When a ray is reflected the incident angle is quizlet?
Rays will follow the law of reflection, so the angle of reflection will be
35°
.
What formula represents Snell’s law?
The exact mathematical relationship is the law of refraction, or “Snell’s Law,” which is stated in equation form as
n
1
sinθ
1
= n
2
sinθ
2
. Here n
1
and n
2
are the indices of refraction for medium 1 and 2, and θ
1
and θ
2
are the angles between the rays and the perpendicular in medium 1 and 2, as shown in Figure 3.
What are the three boundary behaviors?
There are essentially four possible behaviors that a wave could exhibit at a boundary: reflection (the bouncing off of the boundary), diffraction (the bending around the obstacle without crossing over the boundary),
transmission (the crossing of the boundary into the new material or obstacle)
, and refraction (occurs …
What is the incident ray?
An incident ray is
a ray of light that strikes a surface
. The angle between this ray and the perpendicular or normal to the surface is the angle of incidence. The reflected ray corresponding to a given incident ray, is the ray that represents the light reflected by the surface.
What is a boundary behavior?
The behavior of a wave (or pulse) upon reaching the end of a medium
is referred to as boundary behavior. When one medium ends, another medium begins; the interface of the two media is referred to as the boundary and the behavior of a wave at that boundary is described as its boundary behavior.
Why does refraction not occur at 90 degrees?
When the refraction of light occurs, the
incident light rays bend
. If the incident light ray is incident at 90
0
degrees, this means that it is parallel to the normal and it cannot bend away or towards it. … If the light ray doesn’t bend then refraction doesn’t occur.
What happens when waves cross a boundary between air and water?
Waves change speed when they pass across the boundary between two different substances, such as light waves refracting when they pass from air to glass. This causes them to change direction and this effect is called
refraction
. Water waves refract when they travel from deep water to shallow water (or vice versa).
What is bending of light called?
This bending of light is call
refraction
and will result in the light bending into different wavelengths of light displaying a rainbow (spectrum) of color.
